The 5,000 year old assumption that rice grows best anaerobically is now being challenged. Rice grown with drip irrigation not only outproduces conventional paddy rice, but also uses 70% less water, diminishes methane emissions to almost zero, and reduces arsenic uptake by up to 90%.
Healthier, more marketable rice
With paddy farming, rice roots are submerged, consuming heavy metals and skyrocketing the presence of arsenic within the grain, which is a significant health hazard. With drip irrigation, rice roots are not submerged, reducing arsenic uptake by 90%.
Meet the people pioneering precision irrigation
Can I increase my rice yield with drip irrigation?
Yes! With precision irrigation, you can reach a yield of 8 -12 tons/ha – a 50% production increase over production with flood irrigation.
How much water can I save by using drip irrigation?
With drip, you can use up to 70% less water than traditional flood irrigation requires.
Can I grow rice in sloping terrains?
Again, yes! Pressure-compensated dripper lines deliver the precise amount of water required, regardless of pressure changes due to elevation shifts. There is a flexible diaphragm within the emitter which regulates the water flow, guaranteeing no flow variation across the entire field.
Without flooding, how can I control weeds?
Just like when growing any other crop, there are recommended herbicides, ideal times for applications, and mechanical cultivation practices that farmers can easily follow to maximize weed control in aerobic conditions. Drip irrigation also gives farmers easier access to fields for pest and disease control.
Can I grow other crops with the same drip system?
Yes, absolutely. Drip irrigation allows you to rotate several crops on your land, including vegetables like tomatoes or onions, or open field crops including soybeans or corn. Growing legumes in the same field will also improve your soil’s fertility.
